Step-by-step explanation:

1 week = 7 days

given 7 days = 14 hours of practice

and let x be the number of hours spent on practicing and y the number of days.

from the above expression we can have the equation,

y =  \frac{x}{2}

using the equation when y = 10,

\frac{x}{2}  = 10 \\ x = 2(10) \\  = 20

Someone please help me I suck @ simplifying thank you

To solve this question, you would need to find the common denominator among the 2 fractions. In this case it would be

72.

Then multiply numbers to both of the fractions to get to the bottom number in both fractions equaling 72.

40/72 + 27/72 =67/72.

Try to reduce to lowest terms by dividing a common number from both of them if possible.
